What is AI Memory?
Mechanisms that allow AI systems to retain and recall information across conversations and sessions.
Definition
AI memory refers to techniques that enable language models to maintain information beyond their immediate context window. Short-term memory includes the conversation context within a single session. Long-term memory systems store user preferences, past interactions, and learned facts in external databases that are retrieved when relevant. Implementations include: conversation summarization (compressing past interactions), vector store retrieval (semantic search over past conversations), explicit memory writes (user tells AI to remember something), and structured profiles (maintained user preference documents). ChatGPT Memory, Claude Projects, and custom RAG implementations all address the AI memory challenge differently.
Examples
Why It Matters
Memory is what transforms AI from a stateless tool into a personalized assistant. Without memory, every conversation starts from scratch, requiring you to re-explain context and preferences each time.
Related Terms
Retrieval-Augmented Generation (RAG) — Advanced
An advanced architecture that retrieves relevant documents from external sources to ground AI responses in factual data.
Semantic Search
Search that understands the meaning of queries rather than just matching keywords, using vector embeddings.
Prompt Chaining
Breaking complex AI tasks into sequential prompts where each step's output feeds into the next step's input.
Grounding
Connecting AI outputs to verifiable sources and real-world data to reduce hallucinations and improve factual accuracy.
